Tremendously helpful if you need offlin map

I visited Paris for a week, and this app was a lifesaver. It lets me find my current location on the map of Paris, *with no Internet access*. It has an overlay that shows Metro stations. You can search for addresses (though not "Eiffel Tower"). You can get a route between locations.

There are a few problems. One day, the app stopped displaying map images, and would not recover until I deleted the app and reinstalled it. It is not easy enough to tell it to calculate a route starting at "my location". It does not know where "Eiffel Tower" is.

But these complaints are small compared to how useful this app has been to me during my week in Paris (when no Paris mobile phone store would sell me a SIM that would give me Internet access on my unlocked AT&T iPhone 4S).
